Vinylbilt vinyl windows feature the warm edge stainless steel EndurIG™ spacer bar from Cardinal Glass Industries. The EndurIG™ is engineered to reduce heat and cold transfer between the glazing panels, increasing the overall insulation value of your windows. This technology keeps inside air cooler in the summer and warmer in the winter.
